- To all whom it may concern/.- as indicated at B. The quantity of liquid Be it known that l, AUGUST GLEBSATTEL, will be such as not to till the vessel comdirector, asubject of the King of Prussia, Empletely, but will leave a space therein to alperor of Germany, residing at Arndtstrasse low of the expansion of the liquid incident 55 ll, Steglitz, near Berlin, Prussia, German Emto the freezing process.

Besides, fish, venison, meat, and the like when packed in ice often is frozen and then of inferior quality and market-price, while ice vessels can be applied in such number and shapes just as to produce the cooling to the extent required or desired in each case.v For technical purposes the new device will be advantageously applicable in many cases where a more or less sudden reduction of temperature is required and obtained by direct addition of broken ice, though the liquids or materials to be cooled would preferably be kept entirely free from mixing with the melting ice. The manufacture of margarin, for instance, requires a rapid cooling of the melted fat, so as to prevent the fat from turning granular. For brewers and distillers also the mashing process at a certain stage requires a sudden cooling to prevent, as far as possible, the development of lactic acid. and similar cases the ice vessels of appropriate material conducting heat rapidly and in such forms as to adord the relatively largest surface will grant a Wellregulated, rapid, and uniform coolingpIC-ss'Withoutanyinjuring of the substance to be cooled.

In all these will further prove of great For medical and surgical purposes all the advantages of the new device-viz., the stability of shape or form best applicable, the uniform cooling, the constant dryness, and the hygienic accomplishments-are still more significant and of greater consequences.

Vhat I claim, and desire to secure by Letters Patent, is

l. A portable permanently and hermetically sealed vessel having therein frozen liq` uid, the vessel to be submitted from time to time to freezing procedure,retainingits original shape and remaining unruptured and, in use to effect refrigeration, having its operative surface or surfaces free or uncovered by any non-conductive or insulating substance, substantially as described.

2. A portable hermetically-sealed vessel containing frozen liquid, the vessel, to be submitted from time to time to freezing procedure and when in use, having its surface .exposed, that is, when in use, to effect refrigeration having its operative surface or surfaces uncovered by non-conductive or insulating substance being unruptured and o practically permanentshape,substantially as described.

e 3. A hermetically-sealed vessel of heat-con- 65" i ductive substance, containing ice for use asf a refrigerant body, substantially as set forth.

In witness whereof I subscribe my signature in presence of two witnesses.
